ASME SA1017 Grade 23 Steel Plate | SA-1017 Gr.23 2.25Cr-1.6W Vessel Plate

ASME SA1017 Grade 23, also searched as SA-1017 Gr.23, SA1017GR23, SA-1017M Grade 23, SA1017-23, ASTM A1017 Grade 23, T23 plate, P23 plate and 07Cr2MoW2VNbB, is the Section II, Part A name for 2.25Cr-0.20Mo-1.60W pressure-vessel plate. SA-1017/SA-1017M is identical with ASTM A1017/A1017M for the ASTM edition listed in that Code year. General requirements follow SA-20 / A20.

This page is not ASTM A387 Grade 22 Class 2. Grade 22 is 2.25Cr-1Mo with no 1.60% tungsten window. This page is not ASTM A387 Grade 22 Class 1. This page is not ASTM A387 Grade 21 Class 2. This page is not SA-1017 Grade 911 or Grade 92.

Tensile is 74–100 ksi / 510–690 MPa. Yield is 58 ksi / 400 MPa min. Elongation is 20% in 2 in. Hardness on Grade 23 shall not exceed 220 HB. Delivery is normalized and tempered. Typical austenitize is 1900–1975 °F / 1040–1080 °C. Typical temper for Grade 23 is 1350–1470 °F / 730–800 °C. SA-1017 does not split Grade 23 into Class 1 and Class 2.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We buy this grade from qualified Chinese mills, check W, V and Nb on the heat analysis, record N+T and hardness on the certificate, and ship plate to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.

2.25Cr-1Mo sisters without tungsten belong on ASTM A387 Grade 22 Class 2 and EN 10028-2 10CrMo9-10.

SA-1017 Grade 23 uses the same chemistry table as A1017 Grade 23. Do not read it as SA-387 Grade 22.

Heat Analysis and Product Analysis — ASME SA-1017 Grade 23

If tungsten is missing and molybdenum is 0.90–1.10%, the heat is ASTM A387 Grade 22 Class 2, not Grade 23. If chromium is 8.5–9.5%, the heat is Grade 911 or Grade 92. SHH STEEL prints heat analysis on every certificate. Density is 7.85 g/cm³.

Buyers search SA-1017 Gr.23 mechanical properties, SA1017GR23 yield, T23 plate tensile and 07Cr2MoW2VNbB hardness.

Tensile, Yield and Hardness — ASME SA-1017 Grade 23

Grade 22 Class 2 is 515–690 MPa / 310 MPa and does not carry the 220 HB cap written for SA-1017 Grade 23. Grade 911 and Grade 92 sit at 620–840 MPa / 440 MPa. Do not quote those 9Cr numbers on a Grade 23 order.

SA-1017 Grade 23 and A1017 Grade 23 are the same chemistry and the same tensile table. They are not automatic substitutes for Grade 22 or every Chinese 2.25Cr heat.

In the United States the two official current names are ASME SA-1017 Grade 23 and ASTM A1017 Grade 23. Tube and pipe jobs use T23 / P23. Plate still has to meet SA-1017 when the specification is plate. ASTM A387 Grade 22 Class 2 is 2.25Cr-1Mo without tungsten.

In Europe the usual 2.25Cr-1Mo comparison is EN 10028-2 10CrMo9-10 or EN 10028-2 11CrMo9-10. See EN 10028-2. Those pages are not Grade 23.

In China the nearest official name is GB/T 5310 07Cr2MoW2VNbB (also searched as 07Cr2MoWVNbB). That book is seamless steel tubes for high-pressure boilers, not a plate book. Chinese mills that roll SA-1017 Grade 23 plate often dual-discuss T23 / 07Cr2MoW2VNbB chemistry, but the plate certificate still has to say SA-1017 Grade 23 / A1017 Grade 23. GB/T 713 12Cr2Mo1R and 15CrMoR are 1–2.25Cr-Mo vessel plates without the 1.6% W window. Do not treat them as T23.

Dual marking is possible only when both books are fully met.

Buyers pick SA-1017 Gr.23 when a Code list or mill requisition writes the ASME name for T23 / P23 plate. Search phrases such as SA1017GR23, SA-1017 Grade 23, SA-1017M Grade 23, T23 plate, P23 plate and 07Cr2MoW2VNbB all point here.

It is not a substitute for ASTM A387 Grade 22 Class 2. That grade has about 1% Mo and no 1.6% W. It is not a substitute for GB/T 713 12Cr2Mo1R.

SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia.

SA-1017 Grade 23 is killed 2.25Cr-0.20Mo-1.60W-V-Nb vessel plate at 510–690 MPa. Treat welding as production welding, and as ASME Section I / Section VIII welding when the equipment is Code work.

Qualify to Section IX and the construction section named on the job. Consumables must match a T23 / P23 family. A procedure written for ASTM A387 Grade 22 Class 2 is 2.25Cr-1Mo, not Grade 23. Preheat, interpass and PWHT must stay inside the qualified WPS. Grade 23 hardness is already capped at 220 HB; the weld procedure has to respect that cap if the file carries it into the weld zone. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL for SA-1017 Gr.23 is normalized and tempered.

• Austenitize: 1040–1080 °C (1900–1975 °F)
• Temper for Grade 23: 730–800 °C (1350–1470 °F)

Grade 911 in the same book tempers at the tighter 740–780 °C band. Do not mix the two temper tables.

Annealed plate cannot be SA-1017 Grade 23.

If the vessel will see PWHT, say so. Simulated PWHT on test coupons is worth naming. Extra simulation, 3.2 hold points or special NDE add time. Plan about two months when those extras are on the order.

The certificate lists ASME SA-1017 Grade 23 and/or ASTM A1017 Grade 23 as the order named; heat number; heat analysis including W, V and Nb; tensile to the Grade 23 table; hardness not over 220 HB; heat-treatment route and temperatures. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for SA-1017 Gr.23 2.25Cr-1.6W vessel plate:

• Thickness: commonly 6 mm – 150 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Maximum thickness is limited by the ability of the composition to meet the Grade 23 tensile and 220 HB tables. 2.25Cr-1Mo plate without tungsten belongs on ASTM A387 Grade 22 Class 2.

Dimensional limits for ASME SA-1017 Grade 23 follow ASME SA-20 / ASTM A20 unless the purchase order names another table.

Typical thickness tolerance idea for SA-1017 Gr.23 (SA-20 / A20 reference)

Width on 1500–4000 mm plate is commonly held to about ±20–25 mm unless a tighter extra is named. Length on 3000–12000 mm plate is commonly held to about +50 / 0 mm or ±25 mm by mill practice. Flatness follows SA-20 / A20 unless a tighter class is written. SHH STEEL will not assume a zero-minus extra on SA1017GR23 unless the order says so.

SA-1017 Grade 23 already defines chemistry, the 510–690 MPa table, 220 HB max and N+T. Extra items still have to be written on the purchase order.

Book name. Write SA-1017 Grade 23, A1017 Grade 23, or both.

Code year. Name the BPVC edition so the ASTM revision on the MTC can be checked.

Heat-treatment route. Write normalized and tempered. Do not accept annealed plate.

Hardness after PWHT. Repeat the 220 HB cap on simulated coupons if the file needs it.

Charpy details. Write temperature, joules, location and orientation if impact is required.

Simulated PWHT. Name hold temperature, hold time and cooling rate on the coupon.

Product analysis. Especially C, Cr, Mo, W, V, Nb, P and S.

Through-thickness / Z-test. Name Z15, Z25 or Z35 when needed.

NDE. SA-20 / A20 ultrasonic extras, ASTM A435 or ASTM A578 as named.

Third-party witness. EN 10204 3.2 with SGS, TÜV, BV, ABS, CCS, DNV or the inspector named.

Identification and stamping. Heat number, SA-1017 Grade 23 / A1017 Grade 23, thickness and mill logo.

SA-1017 Grade 23 is the plate for a file that wants the ASME name on T23 / P23 / 2.25Cr-1.6W. It is the wrong plate for 2.25Cr-1Mo. That work is ASTM A387 Grade 22 Class 2. It is the wrong plate for P92. That work is SA-1017 Grade 92.

Experience on this grade is simple: print SA-1017 when the order writes SA-1017, keep 1.6% tungsten on the certificate, and keep Grade 23 away from A387 Grade 22. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices SA-1017 Gr.23 from first-line mills, reports 2.25Cr-0.20Mo-1.60W chemistry, records N+T and 220 HB max, and issues 3.1 as standard or 3.2 when specified.

We keep the grade on the order. SA1017GR23 is not ASTM A387 Grade 22 Class 2. SA-1017 Grade 23 is not EN 10028-2 10CrMo9-10. SA-1017 Grade 23 is not GB/T 713 12Cr2Mo1R. If the drawing says Grade 22, we will not ship Grade 23 and call 2.25Cr enough.

ASME SA1017 Grade 23 Steel Plate is 2.25Cr-0.20Mo-1.60W pressure-vessel plate at 510–690 MPa tensile, 400 MPa yield and 220 HB max, identical with ASTM A1017 Grade 23. Whether the inquiry says ASME SA1017 Grade 23, SA-1017 Gr.23, SA1017GR23, SA-1017M Grade 23, A1017 Grade 23, T23 plate, P23 plate or 07Cr2MoW2VNbB, SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) supplies plate with Grade 23 chemistry, the Grade 23 tensile and hardness tables, recorded N+T delivery, and EN 10204 3.1 or 3.2 certification.
